ming perspective, the history of Bank of America dates back to October 17, 1904, when Amadeo Pietro Giannini founded the Bank of Italy in San Francisco. In 1922, Bank of America, Los Angeles was established with Giannini as a minority investor. The two banks merged in 1928 and consolidated with other bank holdings to create what would become the largest banking institution in the country. In 1986, Deutsche Bank AG acquired 100% of Banca d'America e d'Italia, a bank established in Naples, Italy, in 1917 following the name-change of Banca dell'Italia Meridionale with the latter established in 1918.[citation needed] In 1918, another corporation, Bancitaly Corporation, was organized by A. P. Giannini, the largest stockholder of which was Stockholders Auxiliary Corporation. This company acquired the stocks of various banks located in New York City and certain foreign countries. In 1918, the Bank opened a Delegation in New York in order to follow American political, economic and financial affairs more closely. In 1928, Giannini merged his bank with Bank of America, Los Angeles, headed by Orra E. Monnette. Bank of Italy was renamed on November 3, 1930, to Bank of America National Trust and Savings Association, which was the only such designated bank in the United States at that time. Giannini and Monnette headed the resulting company, serving as co-chairs. Expansion in California Giannini introduced branch banking shortly after 1909 legislation in California allowed for branch banking in the state, establishing the bank's first branch outside San Francisco in 1909 in San Jose. By 1929 the bank had 453 banking offices in California with aggregate resources of over US$1.4 billion. There is a replica of the 1909 Bank of Italy branch bank in History Park in San Jose, and the 1925 Bank of Italy Building is an important downtown landmark. Giannini sought to build a national bank, expanding into most of the western st ates as well as into the insurance industry, under the aegis of his holding company, Transamerica Corporation. In 1953 regulators succeeded in forcing the separation of Transamerica Corporation and Bank of America under the Clayton Antitrust Act. The passage of the Bank Holding Company Act of 1956 prohibited banks from owning non-banking subsidiaries such as insurance companies. Bank of America and Transamerica were separated, with the latter company continuing in the insurance sector. However, federal banking regulators prohibited Bank of America's interstate banking activity, and Bank of America's domestic banks outside California were forced into a separate company that event
